Questions & Answers

Question:

We are considering this for venting a bathroom fan out to a rubber-covered flat roof. We have a rubber flange that looks like a witches hat which you cut down to the correct size to allow the vent to pass through it. Do we stick this down over the metal flange? If so, what are the dimensions of the metal flange so I can check our rubber "witches hat" flange will cover it?

Answer:

Yes — your rubber “witches‑hat” EPDM flange does get bonded over the metal flange on the Ubbink OFT‑1F.

The metal flange on the 110 mm model is 330 mm in diameter, so your EPDM boot must comfortably cover at least that area
